They are more than just black round things that stop your rims from scraping on the ground.

There are many different tread patterns available for varying terrain. Choosing the right type of tyre for the riding conditions you will encounter shouldn't be an arduous task. So to help you choose, we've put together a rough guide on what to use on what terrain. Soft Terrain - Loam, mud and sandA tyre designed for soft terrain will usually have taller, sharper knobs (rounder crown radius) that are spaced well apart. The tall knob will bite into the soft dirt and the wider gap between knobs lets the dirt fall back out to avoid it packing. Using a soft terrain tyre on hard packed dirt will reduce the life of the tyres because the taller knobs tend to roll around or squirm under acceleration and braking. This continuous rolling or squirming of the knobs going back and forth will cause them to crack and break off. Intermediate Terrain - Anywhere between hard packed and loose dirt terrainIntermediate tyres are a compromise between hard and soft, offering the best of both worlds.

They are a better option if trailriding as they cover a wider variety of terrain. Hard Terrain - Dry, hard packed conditions including rocky terrain. A hard terrain tyre has large knob blocks with a shorter depth (flatter crown radius) to aid in contact patch. These knobs will be spaced closer together to stop the knobs rolling around (tyre squirming) under acceleration and braking. Due to the hard ground conditions which cause extreme flex and heat, these tyres are generally more supported around the base. motorcycle helmets beijingUsing a hard terrain tyre on soft terrain will give you poor traction due to the knobs being closer together. harley davidson for sale on olxThis results in the tyres clogging with mud and the flatter blocks on hard terrain tyres won't bite into the soft dirt.motorcycle helmet evaluation

Should I run my mountain bike at the suggested PSI/Bar on the tire/rim? Or should I run it a bit lower? Or is it more about conditions? Should I run lower if I am running on softer terrain? Tire pressure is generally a trade-off between three things:red wing boots cheyenne Rolling resistance (more pressure == rolls easier) Pinch flat resistance (more pressure == less chance for the tube to tear when a rock squashes the tire toward the rim) Grip (with less pressure, the tire can conform better to rocks, roots, and other terrain giving a larger contact surface) If you are riding terrain where grip isn't too much of an issue (flat or low-angle dirt and dry rocks for example), then higher pressure will keep you going fast without pinch flatting.

If you are riding steep downhills and/or on slippery open rock outcroppings, grip will be more important than rolling resistance, so use as little pressure as won't pinch-flat quickly. There is a 4th trade-off as well: weight. You can buy double-sidewall downhill tires that allow you to run very low pressures (such as 25psi) without any danger of pinch-flatting, but these can weigh almost double what normal cross-country tires do. As mentioned in other answers, your tires don't have to be the same pressure. Usually grip is more important on the front tire since most of your weight is on it while descending difficult downhill sections. Similarly, when riding on flat or climbing, most of your weight is over the back tire, so rolling resistance and pinch-flat resistance are more important for the back. I personally ride with a low-pressure (30psi in a tire rated 35-65psi) double-sidewall downhill tire on the front and with a higher pressure (50psi in a tire rated 45-65psi) cross-country tire on the rear.

I sacrifice some weight, but otherwise get the best of both worlds: fabulous grip going down and easy rolling on the flats and climbs. Use your best judgment in going below the rated pressure of the tire, as pinch flats become more likely. If you go below the rated pressure, be sure to test it out on hard impacts (such as a rock-corner) on easy terrain before throwing yourself at high speed down a mountain where a blow-out would be catastrophic. Generally run what the tire says. If you know the terrain is slick rock or really loose and will require more contact between the tire and the surface then make them a bit softer. This will increase the chance of pinch flats though so be careful. I almost always run my front tire a bit softer than my back since most of my weight is on the back tire. Just something I've found that I prefer. It really depends on that the trails are like as well as your weight. If you are riding really flowy trails with few obstacles, jumps, or drops, you can probably ride a bit under 25psi if you are light.

THis will give you significantly more traction and control. If you are riding trails with jumps and drops, you will want to air it up more. With rockier trails, you will want to ride at a higher psi to avoid pinch flats. These are the kinds of trails that I typically ride and I usually go with 30 - 35 psi in the front and 35 - 40 psi in the back. I would say that you should run the lowest pressure you can without the tyre rolling off the rim on corners or burping on rocks. The assumption that harder tyres have less rolling resistance is not necessarily true, here is a study showing the opposite. [updated link, if it breaks again, search Google for "Rolling Resistance Eng Illustrated". The document was originally written by Schwalbe Tires] I agree with the other answers, but my strategy is to run the lowest pressure I can while consistently avoiding pinch flats. There's too many variables to come up with a general answer (bodyweight, trail type, tire manufacturer), but I find that something in the mid-30's is safe for me (200+lbs, xc race courses).

If you want to play it safe, find a safe pressure and add 2-3 psi. Also, always check your tire pressure, taking the few minutes before most rides keeps you riding longer. A tip my friend showed me at the weekend was to take to take a wheel and find a pointy rock. Lean all your weight gently onto the wheel. If the wheel doesn't hit the pointy rock then you're not likely to suffer from a pinch flat. If the rock easily touches the rim then the pressure is too low. This should account for a number of critical variables such as the volume of the tyre and the weight of the rider and the reasoning that you'll hit the rock at speed or on one wheel only (normally each wheel only takes 1/2 your weight). Some very good answers, but I think it's also worth saying that the sidewall gives a maximum not suggested pressure on all the bike tyres I've seen. The only time I ever run my mountain bike tyres at their maximum is if I'm riding on the road and in a hurry. None of the answers mention tubeless tires.
